Apartment dwellers know the difficulty of hanging clothes or towels without broadcasting to the rest of the world. What you need is an indoor rack, and the Slimline might just be the answer. The aluminum rack has hooks for easy mounting on to any door. Hinges allow it to fold with latches locking the drying bars when you don’t need them. It’s still useful though even if it’s folded, thanks to the extra towel bar that remains fixed at the bottom of the rack. $35.
